Wraparound extension in Aylesbury
For homes in Aylesbury, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.

Do you need planning permission for a wraparound extension in Aylesbury?
Planning for a wraparound extension in Aylesbury follows the English householder rules.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Aylesbury like to extend?
Commuter semis and detached houses make up much of Aylesbury, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Wraparound extension questions in Aylesbury
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Do you handle building control in Aylesbury?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
What roof suits a wraparound?
A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
